Skipped to the second half of Online Publishers & Ad Networks. I must have missed the part considering the question of “selling your own ad space, being part of a small ad network or teaming up with a search engine” but I imagine the first two have lots of explaining to do.
Nobody knows what form advertising accompanying short form videos on the web or small form devices will work best. I suggest that it should be as unobtrusive as text ads on a web page, or I will skip your video.
